Earlier this week, West continued his unusual blitz, stopping by the offices of Facebook in Palo Alto, California, to preview several brand-new tracks for a roomful of rather awestruck employees. And he did it a capella while standing on table, no less.

"I've been writing new stuff for the new album and I've just got a couple raps that I really like, so I thought it'd be cool just to say them for you all," West said to the audience of cheering Facebook staffers. "All y'all turn your phones off."

He then launched into a mini set — captured, of course, on YouTube — that featured spoken-word versions of songs reportedly slated for the new album, including "Lost in the World," "Chain Gang" and "Mama's Boyfriend."

"This is actually a bit more like a poem," West said at the top of "Lost," a song about love gone wrong: "You're my devil/ You're my angel/ You're my heaven/ You're my hell," he sneers at one point, then goes on more angrily, "Lost in the plastic life/ Let's break out of this fake-ass party/ Turn this into a classic night."

"Chain Gang" sounds like classic Kanye. It's a swaggering, boastful tune that features couplets like "My teeth already white/ You gonna make me floss for nothing," and "They try to tell me aliens built the pyramids/ I swear, life's a bitch on a pyramid," which the audience greeted with laughter and applause.

The real standout, though, was "Mama's Boyfriend," a deeply personal song about his parents' divorce, from the perspective of a young West.

"It took me 33 years of my life to write [this]. It means a lot to me, and it's called 'Mama's Boyfriend,' " West said, as the room grew quiet. "There's a lot of use of the N-word, but I'm allowed to use it."

What followed was West seething at his mother's new man — "Trying to get to know me, homie just kill the charm/ You ain't interested in me, you're just trying to f--- my mom" — lamenting how divorce changes the lives of children forever ("We are the voices of our parents bad choices/ The aftermath of divorces/ The kids of bitter split-ups,") and finally resigning himself to the fact that, as a grown man, he'd basically "become [his] mama's boyfriend" too.

"Many times in life I've had to deal with moments of doubt," he wrote. "And as it's been a minute since I've performed any fresh material in front of an audience, this could've been one of those moments ... but it wasn't. Your energy was a gift so electric, so genuine, that it really helped me give my best. The energy was so inspiring I had to keep going! I just hope you got as much from me as I got from you ... which was everything!"

West's new album is due in September.
